13 Claims, 13 Drawing Figures PATENTEU SEPZ 5 9 3 SHEEI 1 BF 2 SAFETYACTUATOR MEANS FOR USE WITH AEROSOL DISPENSERS BRIEF SUMMARY OF THEINVENTION It is well recognized that children can readily operate aconventional aerosol unit by merely pressing against the valve actuatingmeans. This can cause a serious and dangerous condition which isinjurious to a child or to others, particularly if the spray is directedagainst the eyes or to any other part of the body. Even if thedischarged contents are not harmful, the unauthorized discharge of samecan result in producing a messy condition. It is therefore the principalobject of this invention to provide the conventional aerosol can withactuating means which will prevent operation of the discharge valve ofan aerosol unit unless there is a simultaneous plurality of digitalcontacts with manual pressure applied thereagainst. This makes itvirtually impossible for a child to simultaneously apply the pluralityof digital contacts with the simultaneous manual pressure that isnecessary and therefore guards against the unauthorized use of such anaerosol dispenser by a child who would not be mature enough to apply thephysical effort and/or have knowledge of the manner in which the valvecan be operated, nor have sufficiently developed manual dexterity tosimultaneously operate three different levers.

Another object of this invention is to provide an actuator whichrequires the simultaneous use of three digital members and thesimultaneous pressure of said digital members to actuate the aerosolvalve.

Another object of this invention is to provide a unit which isrelatively inexpensive to produce and which may be readily secured tothe conventional aerosol container.

Another object of this invention is to provide a unit in which the capis so shaped that the pressible actuating means for operating the capare confined within the circumference of the cap so that the units maybe shipped and stacked with the manually engageable actuating meansmaking no contact with other adjacent stacked units.

This invention, as shown in the several embodiments of FIGS. 1 through13, is adapted for use in connection with conventional aerosolcontainers having depressible valve stems. The conventional aerosolcontainer, indicated by the numeral 10, is provided with a top 12 whichis peripherally clinched to the container to provide an annular rim 14.A closure or mounting cup 16 is peripherally clinched to the top 12 ofthe container in the conventional manner to provide an annular bead 18.The closure or mounting cup 16 has a central opening 20 partiallythrough which extends the conventional valve stem 22 which is springbiased and which is normally maintained in its elevated or raisedposition to close the discharge outlet through said valve stem. When thevalve stem 22 is depressed or pushed inwardly relative to the containerand parallel to the axis of the container then the aerosol material inthe container is discharged through the valve stem, all of which isconventional.

The invention shown in FIGS. 1 through 9 will be first described.

The unit of this invention is formed essentially of two main components,namely, a cap generally designated by the numeral 24 and a toggle-typeactuator generally designated by the numeral 26. Both the cap and'thetoggle-type actuator are each integrally molded by injection molding andare formed of a plastic material. The cap 24 is provided with a hollowbody or shell generally indicated at 28, with the bottom or skirtportion 30 thereof of annular shape, with the bottom edge having anannular inverted L-shaped recess 32 to provide a horizontal shoulder anda vertical annular outer wall which, as shown in FIGS. 4 and 5, isadapted to seat on the annular rim 14 of the aerosol container. Theinterior wall 25 of the cap above the skirt is of annular shape with aslight inward incline from the bottom towards the top.

The exterior surface of the shell body of the cap has a rear portion 34which is of arcuate shape and has a slight inward slope as at 35 fromthe bottom toward the top, as best seen in FIG. 6. The rear portion 34of the shell body is cored out as indicated at 37, principally formolding purposes so that a spacing is provided at the rear of the shellbody between the interior annular wall 25 and the rear exterior wall34'.

The exterior surface of the shell body of the cap is shaped so that itprovides two opposite sides 36 which are recessed inwardly from thearcuate circumference 34- and the opposite sides 36 in the main aregenerally planar and extend substantially parallel to each other buthave a slight inward slope from above the top 38 of the skirt 30 to thetop of the cap. Each side 36 is provided with a rectangular-shapedopening '40 through which the tabs of the toggle-type actuator areadapted to extend, as will be presently described.

The exterior surface of the body of the cap has a front recessed portion42 which is likewise generally planar and has a slight inward slope fromabove the top of the skirt to the top of the cap. The front side 42 isprovided with an elongated opening 44 adjacent the lower end thereof,the purpose of which is to accommodate the spout end of the dischargenozzle which is operatively connected to the toggle-type actuator. Thecap, therefore, is provided with an arcuate-shaped rear 34 and inwardlyextending spaced sides 36 and an inwardly extending recessed frontportion 42.

The exterior surface of the shell of the cap is provided with a top wall45 which is centrally recessed as at 46 to provide raised parallelportions 47. The top of the cap has a central opening 48 bounded by anannular wall or sleeve 49 which extends into the interior of the cap ashort distance below the top thereof. The interior of the cap inwardlyof the top of the skirt 30 is provided with a short annular wall 50terminating in an inwardly extending annular lip 51 which, as best shownin FIGS. 4 and 5, is adapted to engage the annular bead 18 on thecontainer for the purpose of non-detachably securing the cap to thecontainer.

The toggle-type actuator generally designated by the numeral 26, bestshown in FIGS. 4, 5, 7, 8 and 9, is integrally molded of plasticmaterial and comprises a cen tral section 52 with an intermediateadjacent section 53 on each side of the central section and a generallyL- shaped section 54 adjacent each of the intermediate sections 53 andan end section 55 on each side of the L-shaped section 54. A hinge 56 isformed between the central and intermediate sections 52 and 53 and ahinge 57 is formed between the intermediate and L- shaped sections 53and 54 and a hinge 58 is formed between the L-shaped and end sections 54and 55, the material along each of the hinges 56, 57 and 58 being ofless thickness than the material of the sections 52, 53, 54 and 55. Theends of each of the sections adjacent each of the hinges are tapered orinclined, as generally indicated at 60, for all of said hinges.

Each of the end sections 55 has an extension extending perpendicular toits respective end section, which extensions when in abutting relation,as shown in FIGS. 4, and 7, combine to form the button-type digitaldepressible member generally indicated at 61. One of said extensions isindicated by the numeral 62 and the other by the numeral 63. Extension63 is of a generally inverted L-shaped configuration with the innervertical flat wall 64 provided with spaced recesses 65. The otherextension 62 is provided with a plurality of spaced tits 66 which arereceived in the spaced recesses 65 to interlock the two extensions 62and 63. The horizontal top portion 67 of the extension 63 extends overthe extension 62 so that a flat surface is presented which extendsthrough the cap opening for digital engagement. The horizontal topportion 67 is round and the exterior side surfaces of the extensions 62and 63 are curvilinear so that when the extensions 62 and 63 areinterfitted an annular wall is provided which passes inside the annularsleeve 49 of the cap.

Each L-shaped section 54 has a portion 68 extending perpendicular to thesection 54 with said portions 68 forming the tabs which are to besimultaneously and manually engaged when the toggle-type actuator isoperated. The said L-shaped sections 54 each have an extension extendingfrom the opposite face of the section 54, generally perpendicular to thesection 54. One of said extensions designated by the numeral 69 is atright angles to the other extension designated by the numeral 70. Saidextensions 69 and 70 are to engage and abut each other when thetoggle-type actuator is actuated.

The central section 52 is integrally formed with a discharge nozzlegenerally designated by the numeral 72 which comprises a body 74 havinga forwardly and horizontally projecting portion 75. The body 74 has avertical bore or passageway 76 which communicates with the alinedopening 78 in the central section 52. The vertical passageway 76communicates with the passageway 79 in the horizontal portion and anannular shoulder 80 is formed in the vertical passageway 76 which seatson the valve stem 22. A separate tubular duct 82 frictionally fits andis retained within the horizontal portion 75. When the toggle actuatoris within the cap the outer end of the duct 82 will extend toward thecap opening 44 so that the material in the aerosol container isdischarged through said duct when the valve stem is depressed by thetoggle-type actuator. The separate duct 82 may be eliminated if desiredand the projecting portion 75 will serve to discharge the materialtoward and outwardly of the cap opening 44.

When the toggle-type actuator 26 is positioned inside the cap it ispositioned as best shown in FIGS. 4, 5 and 7, in which the extensions 62and 63 of the end sections 62 are positioned substantially verticallyadjacent each other and interlocked, as aforesaid, to form thebuttonlike member 61 which is positioned to extend within the annularwall or sleeve 49 of the cap but extends above the top 46 of the cap 24.

FIG. 4 shows the unit in inactive position, that is, the valve stem 22of the aerosol container remains in its elevated position to close theaerosol container. Pressing the tabs 68 of the toggle-type actuator 26inwardly will cause the hinging sections 54 and 53 to move inwardlyrelative to each other, however, the movement will not be sufficient tooperate the depressible valve stem 22 of the aerosol unit since button61 is not spring biased and is free to move upward in preference to thevalve stem 22 moving downward. Also, when the top button 61 is solelydepressed the hinging sections 54 and 53 will move or hinge outwardlyand no movement will be imparted to the valve stem 22. It is only whenthere is a three point pressure simultaneously applied, such as shown inFIG. 5, namely, when the tabs 68 are manually pressed inwardly and thebutton 61 is pressed down simultaneously that the toggletype actuator ismoved to the position shown in FIG. 5 wherein the inwardly facingextensions 69 and 70 abut each other and cause the sections 54 and 53 toassume the position shown to depress the valve stem 22 for the purposeof discharging some of the contents from the aerosol container, thecontents being discharged laterally through the duct 82. Not until thereis a three point pressure applied to the toggle-type actuator will theaerosol valve stem 22 operate to an open position. This makes itvirtually impossible for a child to operate the aerosol unit andprovides the safety factor. Simultaneous manual pressure against any twoof the manual pressure points will not operate to open the aerosol valveas all three pressure points must be simultaneously operated. When themanual pressure is released the aerosol valve stem 22 will by the actionof its spring return the valve stem 22 to the closed position and theparts will be restored to the position shown in FIG. 4.

When the aerosol container with the herein described unit is stackedwith others either on a store shelf or packed in a shipping carton, thetabs 68 of adjacent units will not engage or affect the tabs of anyother units and likewise the button 61 will be free of contact. Even adownward pressure solely on the button 61 will not cause operation ofthe valve stem 22.

The embodiment shown in FIGS. through 13 will now be described.

The conventional aerosol container and the valve stem thereof heretoforedescribed will be indicated by the same numerals as heretofore and willnot be redescribed. The unit of this embodiment likewise comprisesessentially two main components, namely, a cap generally designated bythe numeral 90 and a toggletype actuator generally designated by thenumeral 92. Both the cap and toggle-type actuator are each integrallymolded by injection molding and formed of a plastic material.

The cap 90 is shaped similarly to the cap 24 previously described andwill be only briefly described herein. The cap 90 has a'hollow body orshell with the bottom or skirt portion thereof of annular shape andsimilar to that previously described to engage the aerosol container.The exterior surface of the cap 90 has a front recessed portion 94similar to the front 42 of cap 24, two opposite planar sides 96 whichare recessed similar to the sides 36 of cap 24, and has the arcuateshaped rear 98 cored out as at 97, all as previously described. It alsohas a top 99 and a top opening 100 and a front opening 102 similar tocap 24.

The principal difference between the cap 24 and the cap 90 is that cap90 is provided on each of the opposite planar sides 96 with anintegrally formed digital engageable flap 104 which is of generallyrectangular shape and is connected at the bottom to the body of the capand said bottom forms the hinge line 106 forsaid flap. The oppositesides 108 and the top 1 10 of said flap 104 are disconnected from thecap by a slight spacing, thus, the flaps 104 may be digitally engagedand manually pressed inwardly when they are to operate the toggle-typeactuator 92, to be hereinafter described.

The toggle-type actuator used in this embodiment and generallydesignated by the numeral 92 is generally similar to that previouslydescribed and is integrally molded of a plastic material and comprises acentral section 112 with an intermediate adjacent longer section 114 oneach side of the central section and a short section 116 adjacent eachof the intermediate sections and a short end section 118, with one ofthe end sections provided with an inverted L-shaped extension 120 andthe other end section provided with an extension 122 which is adapted tointerfit with the L-shaped extension and to be locked thereto withinterengaging recesses and tits as previously described to form adigital operated button generally indicated at 124. Since thetoggle-type actuator is generally similar to that previously describedit will not be described in greater detail other than to specify thatbetween each of the sections there is a hinge which is integrally formedwith the actuator, the hinge being of less thickness than the materialforming the sections, as previously described, and with the endsadjacent the sections being tapered.

The difference in the toggle-type actuator 92 from the actuatorpreviously described is that the intermediate sections 114 are eachprovided with a short extension or tab 115 perpendicular to section 114adjacent the hinge line of section 1 16. The outer end of the extensionor tab 1 is tapered. The extension or tabs 1 15 are to be engaged by theside flaps 104 when the flaps are pressed inwardly, as best seen in FIG.ll.

The central section 112 is integrally formed with a discharge nozzlegenerally indicated at 126 and is slmilar to the discharge nozzlepreviously described. The

discharge nozzle 126 fits on the aerosol valve stem 22.

The discharge nozzle 126 dispenses the material through the frontopening 102 of the cap.

When the toggle-type actuator 92 is positioned inside the cap it isnormally in the position best shown in FIG. 10, with the side flaps 104of the cap vertically positioned and substantially coplanar with thesides of the cap and out of engagement with the tabs 1 15 of theactuator. This is the inactive position and the aerosol valve, willremain closed. Applying digital pressure against the two side flaps 104will cause them to engage the tabs on the actuator but will not causethe toggle-type actuator to move sufficiently downward to operate theaerosol valve since button 124 is not spring biased and is free to moveupward in preference to the valve stem 22 moving downward. Also, if thetop or button 124 of the actuator is depressed alone it will not besufficient to open the aerosol valve since the toggle is free to bendoutward. It is only when the side flaps 104 are simultaneously pressedinwardly and the top button 124 is pressed downwardly, allsimultaneously, as shown in FIG. 11, that the toggle-type actuator willdepress the aerosol valve stem to permit the aerosol container todischarge some of the material through the dispensing nozzle 126. Whenthe digital pressure is released the aerosol valve will close to preventdischarge of the aerosol material.

The modification as herein described operates substantially like thedevice previously described, in the sense that there is a threepoint'digital contact at which manual pressure must be simultaneouslyapplied to effectuate the discharge from the aerosol container. Whenmanual pressure against the flaps is released they will return to theirvertical position.

' In the embodiment shown in FIGS. 1 through 9, the pressure is appliedby digital engagement with the tabs of the toggle-type actuator, whereasin the embodiment shown in FIGS. 10 through 13 the same action isproduced by applying digital pressure against the flaps of the cap,which in turn impart a similar action to the toggle-type actuator.
